Exposing the Session Object as a User Defined Class

Introduction

It has been known to happen that, values strored in the Session object can become numerous enough to be unwieldy, ambiguous and often developers will just plain forget what they have stored there. Recently I decided to simplify the matter for myself and began to use an object that I named a SessionSink and placed all session values in the sink object rather than having (n) number of variables making for clutter and difficulty in management. By using the SessionSink we can encapsulate all Session values into one object stored in the Session object. Furthermore we are able to use all the encapsulation practices afforded to us by wrapping it all up in one single user defined class.

The code below is an example of one such SessionSink and can be referred to in code as per the following code snippet:

private void someMethod()
{
    ((SessionSink)(Session["SessionSink"])).GetSetSiteLocationId = 1;
}

Making sure you cast the sink object will give you access to all it�s publicly exposed members. You can initialise the sink in the global.asax Session_Start event method like this:

protected void Session_Start(Object sender, EventArgs e)
{
    Session["SessionSink"] = new SessionSink();
}

Here is the example SessionSink

using System;
using System.Data.SqlClient;
namespace MySessionSink
{
    public class SessionSink
    {
        //Hide these and expose with accessor mutators

        private bool init;
        private string user;
        private string pwd;
        private int CoLocationId;
        private int SiteLocationId;
        private string SlaDepot;
        private int SlaDepotDistance;
        private int RegionRadiusId;
        private string pCode;

        public SessionSink()
        {
            this.init = true;
        }
        //Re-set all the session values

        
        public void Refresh()
        {
            this.pCode = "";
            this.RegionRadiusId = 0;
            this.SlaDepotDistance = 0;
            this.SlaDepot = "";
            this.SiteLocationId = 0;
            this.CoLocationId = 0;
            this.AddUpdateSite = false;
            this.AddUpdateCompany = false;
            this.init = false;
        }

                return this.pwd;
            }
            set
            {
                this.pwd = value;

        }

        public string GetSetUserName
